[BIP-306] Proposal to deploy Balancer on Scroll

Summary

Scroll is live on the Goerli Testnet today and is expected to launch on Mainnet in early August this year. We view Balancer’s composable liquidity products as critical building blocks of decentralized finance and we want to work with you to further expand your growth on Scroll into the future.

If approved, Balancer contributors will launch on Scroll as soon as possible after our Mainnet launch. This would add Scroll to the list of networks approved as new deployments by governance.

Background

About Scroll

Twitter: https://twitter.com/Scroll_ZKP Forum: https://community.scroll.io/

Scroll is an L2 scaling solution that is pushing the development of an Ethereum-equivalent zkEVM. Our main priorities are to implement a bytecode-level compatible zkEVM with sound zero knowledge proofs, work on related initiatives to coordinate the development of Layer 1 and zkEVM, and reach a community standard to improve Ethereum for the end game. Security is of the highest priority for us and our current EVM implementation is well-specified and robust. Our in-house security team also operates in close conjunction with the highest-caliber auditors in the industry.

Scroll is built on a completely open source basis. This includes the ZK circuits, the proving system, and the verifier smart contract. Code security is also closely monitored by community developers from projects such as Zcash, 0xPARC, Privacy and Scaling Explorations, and Filecoin.

Today, Scroll is currently live on the Goerli Testnet and contracts can be deployed permissionlessly by anyone anywhere. We maintain a trustless Layer 1 <> Layer 2 bridge that supports arbitrary message delivery. The bridge is part of the rollup mechanism, verified by the smart contract and the zkEVM, which is more secure than classical relayer-based bridges.

Goals

We propose for Balancer to deploy on Scroll as early as possible (pending Scroll’s Mainnet launch). The Scroll Foundation will actively ensure that early dApp deployments to Scroll will run sustainably after launch.

On our side, there is growing interest from Lending Protocols (including Aave) and Liquid Staking Protocols such as Lido and Rocket Pool for Balancer to deploy on Scroll. These protocols have shown interest in expanding their existing efforts with Balancer onto Scroll, which signals to us that the deployment of Balancer on Scroll is a high-priority task. We want to enable opportunities for Balancer to solidify a strong position in the Scroll ecosystem early on to bring value to both of our communities.

Current areas where we see Balancer playing a key role include:

• Supporting Liquid staking derivative projects seed liquidity for their respective assets on Scroll
• Utilizing Cross-chain gauge boosts to leverage Aura Finance following LayerZero’s deployment on Scroll

We will also actively discover areas within our ecosystem where Balancer’s offerings will find fit, and make those connections accordingly with the DAO.

Specification

If approved, Balancer contributors will launch on Scroll as soon as possible after our Mainnet launch. This would add Scroll to the list of networks approved as new deployments by governance.
